Server DDR4 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR4 2666 MHz registered DIMMs with ECC and a CAS latency of CL19. It is built for servers and workstations that require registered memory and cannot be used in standard desktop or laptop computers.

Registered DDR4 interface limits

The modules operate at 1.2 V and use the 288 pin DDR4 form factor with a single rank x4 organisation. Systems must support DDR4 registered ECC memory and quad channel architecture to utilise the full kit; consumer platforms that accept only unbuffered DIMMs will not work.

Installation notes

Insert each module into the correct memory slots following the motherboard manual for quad channel population order. The registered buffer adds a clock cycle, so the BIOS must be configured for registered DIMMs; mismatched rank configurations or mixing with unbuffered memory will prevent the system from posting.

Questions about this item

Should I choose the 4 x 16 GB kit or a different capacity for my server?

The kit supplies 64 GB total across four 16 GB modules, giving you a quad-channel population that matches many server memory architectures.

What does the 2666 MHz rating mean once the modules are installed?

The DDR4 2666 (PC4-21300) speed sets the maximum data rate; actual throughput depends on the platform's memory controller and how many DIMMs populate each channel.

How does the 288-pin RDIMM interface limit what I can use this memory with?

The 288-pin registered DIMM form factor fits only DDR4 server and workstation boards that support ECC RDIMMs; it will not work in desktop or laptop slots.
